"9 Claims. (crew-1 7) This invention relates to looks adapted to be tightly positioned in their keepers, and which may be readily disconnected from and re-connected to the control of their operating handles.

A principal object of the inventionis to. provide a lock which will be held tightly in its keeper,

and thus be prevented from rattling.

Another principal object is, by a simple manual operation, to throw the operating handle of the lock out of control of the lock itself, and in this Way to prevent the lock from being operated until the same has been reset for such purpose.

Another principal object of the invention is to adapt the lock to be reset for manual control by the handle.

Another principal object of the invention is to provide means to prepare the lock to be put out of control of the handle, so that the next manipulation of the handle will throw the lock out of such control.

Another principal object of the invention is to provide means for automatically releasing the tightening mechanism.

Other objects will be apparent from reading this specification in connection with theaccomsecured in position on a door, the view being taken fromthe top; p 1

Figure 5 is a fragmentary top plan view illustrating the latching mechanismfor the tightening bolt;

Figure 6 is a vertical section taken along the line 6-6 of Figure 4; and

Figure '7 is a view showing a detail of the mechanism for controlling the elevator platform.

Referring now in detail to the drawings, in which similar characters refer to similar parts throughout, I is a door hinged at H to its support l2. Door-stops are shown at I3.

Mounted on the door lll is my improved lock having a housing, the sides of which are designatecl l4, and the bottom of which is designated l5. Secured to thehousing-bottom I is a stationary block l6 (Fig. 4) ,.on which is mounted in sliding contact the main bolt ll. Thismain bolt is slotted at l8, and is provided with a spring support l9 integral with said bolt, which springsupport carries the coil spring 20. The springsupport I9 extends through the block Hi and isin slidable contact therewith.- Integral with the 5; main bolt l are. guides 2|, 22 and 23 respectively.- These guides are adapted to control the direction of the movement of. the sliding tightener. 24; This tightener is. spring-propelled by the spring 25, mounted on the spring-holder 26, whichlO spring-holder is integral at one end with the block 2|, and extends through a portion ofandis in slidable contact with the slide 24 at the other end. A guide pin 21 mounted in thebolt plate This provided to co-operate with the slot 28 as partv of 1513 the guiding meansto control the direction of the movement ofthe sliding tightener 24.

In the tightener 24 (Fig. 5) is a bifurcated ba or bell-crank 3.0 pivoted in the slide 24, one leg of which terminates in the latch 29, and the other leg of which terminates in the slot 3|, located in the push rod 32 carried by-the tightener, 24. This push rod is normally pressed downwardly by the spring 33 confined in a recess 34 at the end of the push rod 32, on which it acts. A 25. pin 35 is mounted in the bolt plate I! which'the latch 29 is adapted to engage when the tightener slide 24 is in its most forward-position. This latch may be released fromthe pin 35 by pressing the rod '32 which swings the bell-crank and with it the latch. I

The guide block- 2| is'cut away at 36- (Fig. 4) the forward end of such cut-away portion being slightly narrower than and tapering back to the rear portion. The side of the cut-out portion 36' adjacent the sliding tightener 24, is open, the cutout of the guide block and the side of the tightener formingan open oval slot. A spring pressed carriage 31 is in slidable relation with the guide block 2|," which carriage bears the roll 38 which extends into the oval cut-out portion 3B, which roll makes a free contact at the enlarged por tion of the cut out and frictional contact between the'fguide'block 2| andthe tightener 24, as it approaches the smaller end of the cut-out. The 45 purpose of this arrangement is to hold the tightener inrigid'condition with reference tothe bolt plate ll, until the same is released. Releasing means are provided in the form of a lever 39 extendingfthrough the bolt plate H, and having theturned upend 40 which is adapted to press the carriage 31 againstthe spring 4| and thereby force the roll 38 out of frictional conta ct' with theguide block 2| and the slidingtightener 24 55 and thereby again subject the tightener to the action of the spring 25.

Referring to Figures 1 and 2, the operating handle for the lock is designated as 42, which is held in normal position by the spring 43, one end of which is held in the housing-back |5 and the other end is held in the link 44. The handle 42 is mounted to turn the shaft 45, the link 44 also being keyed to said shaft. A pivot-connection is made between the link 44 and the push-bar 41, having the nose 48 integral therewith. Projecting from said push-bar 41 is a guide pin 49, which travels in the track 50. Secured to the bolt-plate |1by the rivet5| is the carriage 52, which pivotally supports the rocking bar 53, the same being pivoted at 54. At the other end of the bar 53 is a lug 55, which, in the position shown in Fig. 2, lies in the path of the nose 48. Upon the handle 42 being pressed downward, the push-bar 41 will move rearward, and the nose 48 will engage the lug 55, carrying the same rearward, and with it the carriage 52 andthe bolt-plate H with its connected mechanism.

The bar 53 is controlled in its pivoted position by the elevator platform 56, the said bar being pressed against the same by reason of the spring 51. The operating mechanism of this elevator platform will now be described. Depending from the housing back I5 is the face plate 58. (See Figure 7.) Mounted in the rear of this face plate is the stud 59, which holds one end of the spring 66, the other end being secured to the underside of the elevator-platform 56. The effect of this spring is normally to pull down on said platform. Secured to the platform is a slide 61 held in slidable position against the face plate 58 by the bracket 6|, and prevented from lateral movement by the stud 59 which, as described, also carries one terminal of the spring 60. The elevated position of the said platform is controlled by the lever 62, which is pivoted at 63 to the face plate 58. This lever is operated by the cam 64 mounted on the shaft 65, operated by the handpiece 66 (Fig. 6). A stud 68 is mounted in the face plate 58 to limit the cam movement in one direction, and a stud 69 is mounted on'the lever 62 to limit the cam movement in the other direction. A spring 10 is provided to hold the cam in set position. A segment 89 (Fig. 3) is keyed to the shaft 65, (Fig. 6), and the link 90 is integral with the collar 9|. Secured to the link 90 is a guide 92 (Fig. 3) in which the periphery of the segment 89 is adapted to slide. The said segment has an aperture 93 (Fig. 6) in line with the rod 1|, the end of which is adapted to be slid into said aperture. To accomplish this, the bifurcated link 12 straddlesthe shaft 65 and is pivoted thereto by the pivot 13. The link 12 is provided with a lip 14 adapted to be engaged by the lip 15 on the lever 16, which lever is pivoted at 11 in the bearing 18. A spring 19 is carried by the rod 1| for the purpose of thrusting the link 12 into constant engagement with the lip 15 of the lever 16. When the lever 16 is drawn down it rests in the recess of the hand-piece 66, and the rod 1| is pressed forward so that the end thereof passes through the aperture 93 of the segment 89 and projects into the path of the link 90. When the rod 1| is extended into the path of the link 80, the movement of said link will cause the rod 1| to rotate about the rod 65, and with it the hand-piece 66, and the elevator-platform 56 will by reason thereof be lowered, and the handle 42 be put out of control of the lock. The said link 98 is pivoted to another link 95, which in turn at its opposite end is pivoted at 96 to the bolt plate l1. The bolt operating mechanism of the lock may be rendered unresponsive to the manipulations of the handle 42 by pressing down the lever 16, which in the manner described will thrust the end of the rod 1| into the path of the link 90. Upon the handle 42 being pressed downward, the bolt |1 will slide in the manner heretofore described and will draw the link 95 and its connected link 90 with the rod 1|, the shaft 65 will be turned, the elevator-platform 56 will be lowered as described and with it the bar 53 and itsattached lug 55, which lug is then removed from the path of the nose 48 of the push-bar 41, and thus fail to move forward the carriage 52 and its connected bolt plate I1.

As above described, the elevator-platform 56 is shown in its lifted position and as a consequence the lug 55 is in the path of the nose 48, which enables the carriage 52 to slide the bolt l1 and its connected mechanism upon the manipulation of the handle 42. In case it is desired to disconnect the sliding bolt mechanism of the lock so that manipulation of the handle 42 will have no effect upon the same, the hand-piece 66 is turned, which effects the lowering of the elevator-platform56, and with it the bar 53 with its connected lug 55, dropping the same out of the path of the nose 48. When the elevator-platform is in its lower position, manipulation of the handle 42 will have no control over the carriage 52 and its connected sliding bolt l1 by reason of the following mechanism. Mounted on the pushbar 41 (Fig. l) is a bracket 8|, in which is pivotally mounted at 82 the rockable bar 83. This bar is spring held in the position shown in Figure l, and is provided with the stop 84 to limit its spring pressed position. This bracket 8| is stepped at 85, the step being adapted to engage the lever 39 and carry the same rearward upon manipulation of the handle 42. The elevator-platform 56 bemg in its lowermost position as last described, the movement of the pushbar 41 being unrestrained by the lug 55, will permit the rocking bar 83to continue rearward in its travel, and upon engaging the roller 86 carried by the bracket 81 mounted on the cover plate 88, will depress the raised end of said bar 83, and thereby raise the step out of the path of the tightener-release-lever 39. It will now beseen that manipulation of the handle 42 while the lock is in this position, will exercise no control on either the bolt IT or the tightener 24.

In operation, upon a door carrying my lock being closed, the main bolt [1 will be pressed inwardly by its contact with the strike plate 91 until it passes the same, when the bolt will be spring-pressed forward into its keeper 98, the edge of the strike plate 91 which is in the path of the release rod 32, presses the same and thereby unhooks the latch 35, and restrains the tightening bolt 24 from further forward movement with the main bolt |1. As the main bolt extends forward after the restraining of the tightening bolt, the latter expands laterally with reference to the main bolt and efiects a tightened fit of the bolt in its keeper 98. This tightening is due to the inclination of guides 2|, 22 and 23, in which the tightening bolt 24 operates. As the main bolt moves forward and the tightening bolt is restrained, the roll 38 will assume a position in the narrow part of the cutout portion 36, and will operate upon the tightening bolt and frictionally hold the same in position until the same is released by the lever 39.

If it is desired to interrupt the control of the handle 42 upon the lock so that upon manipulation of the same it will not operate the lock, the hand-piece 68 is turned so as to allow the elevator-platform 56 to be lowered, which will remove the lug 55 out of the path of the nose 48, thereby exercising no influence upon the carriage 52 or the bolt H to which said carriage is attached. The operation of the handle 42, when the lock is in this position, will carry rearward the pushrod ll until the elevated end of the rocking bar 83 passes under the roll 86, depressing the said elevated end of the rocking bar and elevating the opposite end thereof, and thereby withdraw the step 85 out of the path of the tightening-boltrelease-lever 39, which in consequence will be uninfluenced by the manipulation of the handle, when the lock is in this position. Instead of manually turning the hand-piece 66, to put the lock out of control of the handle 42, the lever 16 may be drawn down so that the free end thereof will be in the cut-out 80 of the hand-piece 66. The said lever being so drawn down will press forward the rod ll through the segment 89, and the end of the rod H will extend into the path of the link 90, and upon the next manipulation of the handle 62, the link 96 will engage the end of the rod H and turn the same together with the hand-piece and thereby lower the elevatorlatform with the attendant consequences.

In order to put the handle again into control position of the lock, the hand-piece 66 is turned to raise the elevator-platform t, and to move it into this position, the lever 16 is raised to vertical position as shown in Figure 6, thereby permitting the withdrawal of the end of the rod H from the path of the link 96.
